Important Safety Instructions

General installation conditions

• Before handling or connecting this equipment, please read carefully all warnings and instructions in this manual.
• In order to reduce the risk of fire or electric shock, do not expose the equipment to rain or in excessively moisture conditions.
• Do not open the equipment without disconnecting it from the mains.
• Do not obstruct the equipment’s ventilation system.
• Please, allow air circulation around the equipment.
• The equipment must not come into contact with water or even be splashed by liquids. Do not place containers with water on or near the equipment if it is not adequately protected.
• Do not place the equipment near heat sources, like radiators, stoves, heater or other electronic equipment.
• Do not place the equipment where it may be affected by strong vibrations or knocks.

How to use the equipment safely

• If any liquid or object falls inside the equipment, please contact a specialized technician.
• Do not connect the equipment to the mains until all the other connections have been made.
• The mains socket that is going to be used to connect the equipment should be located nearby and should be easily accessible.
• Make sure that all power cords, plugs and cables are not pinched or bent sharply to prevent any possibility of damage, electrical shock or fire.
• Unplug the unit power cord by gripping the plug only.

Input & Output description

General description
Range of amplifiers designed for multimedia distribution in small/medium size buildings.
These amplifiers feature forward and passive/active return path with their correponding range of attenuators and equalizers that provide the optimum adjustment to deliver the right output level in accordance with the installation needs. Amplifier’s setting up is carried out by means of removable
jumpers that allow to select fixed stepped values. The use of jumpers allows an easy reading of each setting.
The active return path is fully configurable by means of plug-in jumpers. Attenuation ranges from 0 to 18 dB in fixed steps of 2 dB. The equalizer is an interstage type ranging from 0 to 6 dB in fixed steps of 3 dB.

The forward path features both configurable input attenuator and input equalizer by means of jumpers in steps of 2 dB. Furthermore, it has selectable interstage attenuation and equalization by means of two double jumpers.

The forward gain is selectable by double jumper, allowing to decrease 0 or 5dB.
Furthermore, it has selectable interstage equalization (tilt), with double jumper allowing 0 or 6 dB
settings.
The amplifier is housed within a die-cast enclosure that contributes to reduce the temperature of its components due to its excellent heat disipation.
An ON/OFF LED indicates when the amplifier is connected to mains. On the other hand, a LED inside indicates if the amplifier is being powered.
Once opened (untightening the screw located on its front), an intuitive diagram of blocks explains how the amplifier works to achieve the desired output level.

Open the amplifier by untightening the screw located on its front lid.
The amplifier block diagram is inside the unit. To set attenuation/equalization, plug-in the jumper into the required value for the installation.
The forward path features separate interstage equalization and attenuation. Two double jumpers can be set in two positions, as indicated in the diagram.
Jumper positioned “=” do not attenuates the signal. Jumper positioned ” =” attenuates the signal by 5 dB.

In the same way you can proceed with the double jumper for the equalization.
Once all settings have been made, close de enclosure and thighten its frontal screw.
